Solidity/Truffle simple payment system between teachers and students

I´m doing an online bootcamp in Solidity and Truffle, and for the final project I need to develop a simple tutor-student payment system. The smart contract need to do stuff like freeing tokens every time a class is given (maybe using multisig) or reimburse tokens after some time if the teacher dissapears, it´s meant to be simple and secure, in this stage it´s not desirable to add extra complexity. Also I need to do a simple React or HTLM frontend for the project, no design required, only functionality and security. All the project must have at least 5 unit tests, 2 swc vulnerability tests, at least 1 inherited library or interface, and be of easy compilation

Most of all I need guidance and help, so we can build this together, hence I have only one month to present this
